To all whom it may concern:

Be it known that T, LUDVIK RASCH, 'of lriagnusgt. 7, Christiania, a subject of the King of Norway, residing at Christiania, Norway, have invented certain new and useful improvements in Pumping Arrangements for Turbine-Driven Separators, of which the following is a specification, reference being had therein to the accompanying drawing.

The object of the present invention is an arrangement of pump in separators driven by means of a turbine-wheel disposed on the separator-spindle substantially for the purpose of combining the pump with the bearing of the driving shaft as well as other parts belonging to the same to a whole so as to be easily fastened in the frame and easily put in and removed from the same for inspection and reparation.

The arrangement is illustrated in the inclosed drawing in which:

Figure l is a sectional view of the frame of a milk separator.

Fig. 2 is a similar view at a right angle to Fig. 1.

Fig. 3 is a plan View of the frame with the pump on an enlarged scale.

Fig. dis a separate View of the pump.

The frame 1 which is arranged as a reservoir for the driving fluid may be cylindrical or preferably have the form of an inverted cone in order to obtain a great base.

The pump cylinder 2 is fastened by means of two ribs 3, 4: to the bearing 5 for the driving shaft 6. The bearing 5 is divided in order to give the necessary space to a lever 7 driving the pumpingpiston. The bearing part 5 is carried through a hole in the wall of the frame; it is provided with a flange 8 provided with packing 9; the said flange having two ears 10 for the fastening pins 11. The inner bearing part 5 is pro vided with a cast block12 for the footbearing of the spindle. The pump cylinder 2 is provided with an car 18 cast to the same arranged so as to be connected to the frame 1 by means of a pin 13. The ear 13 is arranged in such a manner that its fastening point to the frame is placed about at a right angle to the fastening point of the bearing in order to obtain a rigid connection of the pump to the frame.

From the bottom of the pump cylinder passes a channel 14 to a valve box containing a valve 15 for the suction pipe 16 and from a box 15 projects the delivery pipe 17 to a valve box 18 containing a valve 18 for the mouth piece 19.

In great separators it is preferred to connect the driving shaft to a spring which is strained during the suction stroke in order to assist the motion of the pump piston during the pressure stroke. For this purpose the shaft 6 is provided with an arm 20 which is connected at its end to a spring 21 the opposite end of which spring being fastened to an immovable point such as a lug 22 cast to the valve box 15.

The invention also has for its object a suitable arrangement of the connection between the arm 7 and the pump piston. The connection is made in that way that a rod 23 having ball-shaped heads 23 and 23 is placed in corresponding sockets in the arm 7 and the piston, a spring 24 being at its one end connected to the arm 7 and at its other end to the'piston; the piston being provided with a groove which may take up the last winding 24; of the spring. By this arrangement any breaking is prevented and as the said spring forces the parts well together no looseness may occur.

Having now fully described the nature of my invention and the manner in which the same is to be performed I declare what I claim is:

1. In pumping apparatus for turbinedriven separators, a frame having an opening in its wall, a bearing extending through said opening and having a flange secured to said wall, a driving shaft in said bearing, and a pump cylinder having ribs secured to said bearing and also having an ear secured to said frame.

2. in pumping apparatus for turbine driven separators, a reservoir frame, a bearing secured to a wall thereof a driving shaft mounted in said bearing, a pump cylinder in said frame and depending from and secured to said bearing an arm on said shaft, and a spring connected to a fixed point and to said arm and arranged to be put under compression by a suction stroke of the pump piston and to expand and thereby aid the pressure stroke of the piston.

8. In pumping apparatus for turbine ed to said suction pipe and the other end 10 driven separators, a reservoir frame, a been connected to said arm.
